The 5210 Entry SATA solid-state drives (SSDs) are low-cost SSDs for ThinkSystem servers. The drives use Micron 64-layer 3D QLC NAND flash memory technology with a SATA 6Gbps interface and provide an affordable solution for large-capacity sequential read-intensive applications such as AI and machine learning data lakes, real-time analytics, big data, and media streaming.
The 5210 Entry SATA SSD is shown in the following figure.

Did you know?
QLC (quad-level cell) represents the next generation of NAND flash memory technology. QLC means that 4 bits of data is stored in each memory cell which results in more cost-effective drives and larger drive capacities. The target workloads for QLC-based SSDs are sequential read-intensive workloads. For such workloads, QLC SSDs are an excellent cost-effective candidate for replacing 10K RPM HDDs.

The 5210 Entry SATA SSDs have the following features:
- Industry standard 2.5-inch form factor
- New generation 64-layer 3D QLC NAND flash memory
- Suitable for read-intensive sequential workloads with larger block sizes
- 6 Gbps SATA host interface
- High reliability and enhanced ruggedness
- Absence of moving parts to reduce potential failure points in the server
- S.M.A.R.T. support
- Advanced Encrypting Standard (AES) 256-bit encryption
SSDs have a huge but finite number of program/erase (P/E) cycles, which affect how long they can perform write operations and thus their life expectancy. Entry SSDs typically have a better cost per read IOPS ratio but lower endurance and performance compared to Mainstream or Performance SSDs. SSD write endurance is typically measured by the number of program/erase cycles that the drive can incur over its lifetime, which is listed as total bytes written (TBW) in the device specification.
The TBW value that is assigned to a solid-state device is the total bytes of written data that a drive can be guaranteed to complete. Reaching this limit does not cause the drive to immediately fail; the TBW simply denotes the maximum number of writes that can be guaranteed. A solid-state device does not fail upon reaching the specified TBW. However, at some point after surpassing the TBW value (and based on manufacturing variance margins), the drive reaches the end-of-life point, at which time the drive goes into read-only mode. Because of such behavior, careful planning must be done to use SSDs in the application environments to ensure that the TBW of the drive is not exceeded before the required life expectancy.
For example, the 1.92TB drive has an endurance of 700 TB of total bytes written (TBW) with 4KB random writes. This means that for full operation over five years, write workload must be limited to no more than 384 GB of 4K random writes per day, which is equivalent to 0.2 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 639 GB of writes per day, which is equivalent to 0.3 full drive writes per day.
The endurance of the 5210, like other NAND-based solid-state drives, varies depending on the workload. The value of the 5210 SSDs is best achieved when the drives are matched with read-intensive workloads with large-block sequential data access. For example, if all write operations are sequential and in 128KB blocks, the drives can support 0.8 total drive writes per day, which equates to 6,142 GB of data writes per day in the case of the 7.68TB drive option.
The key factors in determining drive endurance are the read/write mix, whether the writes are sequential or random, and the block size. The following table show the different endurance values of the 5210 drives, based on the workload.

Operating system support
SATA SSDs operate transparently to users, storage systems, applications, databases, and operating systems.
Operating system support is based on the controller used to connect to the drives. Consult the controller propduct guide for more information:
The 5210 Entry SATA SSDs carry a one-year, customer-replaceable unit (CRU) limited warranty. When the SSDs are installed in a supported server, these drives assume the system’s base warranty and any warranty upgrades.
Solid State Memory cells have an intrinsic, finite number of program/erase cycles that each cell can incur. As a result, each solid state device has a maximum amount of program/erase cycles to which it can be subjected. The warranty for Lenovo solid state drives (SSDs) is limited to drives that have not reached the maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the SSD product. A drive that reaches this limit may fail to operate according to its Specifications.
The drives have the following physical specifications (approximate, without the tray):
- Height: 7 mm (0.3 in.)
- Width: 70 mm (2.8 in.)
- Depth: 100 mm (4.0 in.)
- Weight: 70 g (2.5 oz)
The SSDs are supported in the following environment:
- Operating temperature: 0 to 70°C (32 to 158°F)
- Non-operating temperature: -40 to 85°C (-40 to 185°F)
- Relative humidity: 5 to 95% (non-condensing)
